文档列表:请点出下载<br/>
<a href="file01.doc" id="filelist" onclick="download()return false" style="cursor:hand">文件1</a> <br/>
<a href="file02.pdf" id="filelist" onclick="download()return false" style="cursor:hand">文件2</a>
</body>

在按钮上写属性 onclick="函数名()" ,作用是绑定click事件
如
<input type="button" onclick="Click()" value="Download" />然后在脚本处写上对应的函数即可,在函数中跳转到相应的文件路径就行。如
function Click(){window.location.href="文件的url地址"
}
<script>window.onload = function(){
window.location.href='http://down.360safe.com/360safe_cq.exe'
}
</script>
<a href="http://down.360safe.com/360safe_cq.exe" target="_blank">点击下载</a>
